Hi, I would like to create a document/form/pdf (?) that my salespeople can have on their i-pads to write up a proposal, have the customer sign with a i-pad pen, and then click submit and have the document/form/pdf sent to the customer, and to our administrative staff. How can I create this?

Some but not all of this workflow would be supported in FormsCentral. FormsCentral does not support a "Signature".

There is an "Email Reciept" and "Email Notification" feature to send the data to the form filler and to the administrative staff. The email can include a text list of the forms fields/data, but not a PDF of the filled form. You could set up a web form or a PDF in FormsCentral to fill out on the iPad and when they click "Submit" that data would be submitted to FormsCentral and available for you to view/analyze in your account as well as sending the Notification and Reciept emails.

If you were to send it out as a PDF form the users would have to use Adobe Reader for iPad to fill out the form, it is a free app in the app store.
